SB timing chain drip tab

Hi all, Ive torn down the front of dads 273 to repair a coolant leak. I noticed that it doesnt have the drip tab that directs the oil from the upper galley to flow out thru "bolt with hole" and directly onto the the timing chain. I would like to install one if it doesnt hold me up too much longer.
I checked both my 67 and 67 factory parts manuals, and neither of those show the drip tab.

What year/size engines had these, so I can try and source from local wreckers.

Thanks
Steve
